.SH NAME
\fBMPI_Win_flush_local\fP, \fBMPI_Win_flush_local_all\fP \- Complete all outstanding RMA operations at both the origin

.SH SYNTAX
.ft R
.SH C Syntax
.nf
#include <mpi.h>
int MPI_Win_flush_local (int \fIrank\fP, MPI_Win \fIwin\fP)

int MPI_Win_flush_local_all (MPI_Win \fIwin\fP)

.fi
.SH INPUT PARAMETERS
.ft R
.TP 1i
rank
Rank of window (nonnegative integer).
.TP 1i
win
Window object (handle).

.SH OUTPUT PARAMETER
.ft R
.TP 1i
IERROR
Fortran only: Error status (integer).

.SH DESCRIPTION
.ft R
\fBMPI_Win_flush_local\fP locally completes at the origin all outstanding RMA operations initiated by the calling process to the target process specified by rank on the specified window. For example, after this routine completes, the user may reuse any buffers provided to put, get, or accumulate operations. \fBMPI_Win_flush_local_all\fP locally completes at the origin all outstanding RMA operations to all targets.
.sp
Can only be called from within a passive target epoch.

.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with \fBMPI_Comm_set_errhandler\fP; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
